It's now believed (after some detective work from Herbert) that this round of problems wasn't caused by the -stable patch, but by a bogus update to Xen which we carry in the Fedora kernel that sneaked in without a changelog (which is why I didn't even suspect that thing given it worked fine previously). Until today I had no idea just how much that thing poked into net/ Ugh. Apologies for the false alarm. Dave -- http://www.codemonkey.org.uk
